IMPROVED PORTABLE SELF-ELEVATOR.

The Schedule referred to in these Letters Patent and making part of thesame.

l, HERt'IAN L. HALL, ofthe city of Buialo, in the county of Erie andState of New York, have invented a certain new and improved PortableSelf-Elevator for Fruit-Picking, and for other purposes, of which thefollowing is a specication.

My invention relates to the combination and ar- /rangement of an uprighttimber, supported upon wheels, a platform, constructed so as to slide upand down upon said timber, and a windlass, with necessary stop and breakupon the platform in such manner that a person may step upon theplatform, and, by turning the windlass, lift himself or herself up tothe extremeheight of the upright timber; an apparatus specially designedfor fruit-picking in orchards, but which is also admirably adapted forcarpenters, painters, plumbers, roofers, and other mechanics whoseoccupation requires them to reach elevated points upon the outside orinside of buildings and other placesralso, for carrying brick and mortarto workmen upon buildings in course of erection, and for many otheruseful purposes.

In the accompanying drawing- Figure I is a side elevation of my improvedselfelevator. l

Figure II is a top plan view.

Letters 'of like name and kind refer to like parts inv each of theiigures.

A represents an upright timber, which is supported in the socket a', orotherwise connected to the horizontal timber B, which, together with theaxle C and wheels c* c2 thereto attached, forms a very simple carriage,by means of which the timber Amay be moved from place to place.

D represents a platform, to the center of which is connected a tube, d',through which the timber A passes, in a manner to permit the platform toslide up and down upon said timber, and to retain the platform in ahorizontal position during such up-anddown movementor at right angleswith the timber.

E represents awindlass and crank, secured by brackets to the tube d',within convenient reach of a person standing upon the plattform.

A rope, f, connected to thewindlass,is passed over a pulley,g, upon thetop of the timber A, and down upon the opposite of the timber, and isattached to a staple, h, upon the tube ll. l

By turning the crank the rope will be wound upon the windlass barrel,and thereby raise the platform.

t' represents a ratchet-wheel upon the windlass, the teeth of whichengage with a stop or dog, j, by means of which the platform may beadjusted and held at any desired elevation.

A brake, 7.1, upon the windlass, is so arranged that when the stop 7' isdisengaged from the ratchet-wheel, thereby lowering the platform, thelatter may be checked in its descent by means of the brake,`and slidedo'wn slowly and gradually. l

A note-hed stake, L is passed through a hole or socket in the extremeend of the timber iB, and secured by means of the pin m, so as to holdthe timt ber A upright.

The timber B forms the pole of the carriage. l

Horses or other draught animals 'may be attached thereto, or thecarriage moved by hand, as'may be most convenient. y

The operation of my improved self-elevating apparatus is so simple thatit will readily be understood by examining the drawing.

Claim..

I claim as my invention The combination and arrangement of the timber A,upon the carriage B C c1 c?, the platform D, the windlass E, with stop jand brake 1t, andthe notched stake L, all parts being constructedandoperating substantially as described and for the purposes set forth.
